Adaptive bitrate streaming is a technique used in video streaming to provide a high-quality viewing experience to users with varying internet connection speeds. Instead of delivering a single fixed bitrate video file, ABR dynamically adjusts the video quality based on the viewer’s network conditions.

Adaptive bitrate streaming (ABR) identifies the viewer’s network conditions in real time and automatically adjusts the streaming bitrate to deliver an optimal viewing experience. Since ABR streaming can adjust the video quality based on network conditions, it is becoming more popular than progressive video streaming.
